A decision can be pressure-tested by prompting a model with fixed, differentiated expert personas (perfectionist, operator, contrarian, brand builder, provocateur, founder) that each supply the public philosophies and thinking style of a named figure, producing a panel rather than a single answer.
This is a concrete recipe for role-differentiated critique: the diversity lives in the persona specification layer, not in the model, so it can be implemented as an orchestration pattern over one base model and reused for red-teaming plans, prompts, or architecture decisions.
Persona-differentiated panels are a cheap substitute for heterogeneous models when building critique, review, or red-team stages; the value depends on whether the disagreement is substantive or merely stylistic.
